DRINKING-CUP.

Application filed October 18, 1911, Serial No. 655,358.

To all whom it may concern:

Be it known that I, JOHN F. BRADY, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inDrinking-Cups, of which the following is a specification.

My invention relates to metallic drinking cups and its essential objectsare facile portability, compactness, freedom from rattling when incollapsed position, non-accessibility to dust, and reversibility of thecover as a base.

To the above ends essentially my invention consists in such novel partsand combinations of parts as fall within the scope of the appendedclaim.

In the accompanying drawings which form a part of this specification,Figures 1, and 2, are bottom plan and side elevation respectively of mycup in housed position, Figs. 3, and 4, sections of the same on lines:0, c0, and 3 y, respectively of Fig.1, Fig. 5, a side elevation partlybroken away of my cup expanded and the housing removed, Fig. 6, asection of the housing on line a, a, of Fig. 1, and Fig. 7, a sideelevation of the cup in expanded position and located in the housing,showing the housing partially broken away.

Like reference characters indicate like My cup has a preferably slightlyconcavo convex base A and its outer edge is rolled over to form a bead,a. Soldered to the up per concave face of this base by solder orotherwise, concentrically therewith and of less diameter than the baseis an upwardly tapering sectional collapsible cup B of increasingdiameter upwardly. In detail this cup comprises a bottom cup shapedmember Z) consisting of a base 7) and an upwardly and outwardly taperingside wall 6 Surrounding the member 6 are a plurality of nested taperingrings 0, of successively greater diameter away from the member B, butwhose smaller several diameters are less than the several largerdiameters of next adjacent inner rings, so that when the rings arepulled outwardly or expanded the member 11 and the telescoping rings 0are frictionally connected and form a complete cup as shown in Fig. 5.The uppermost of the rings 0 has preferably a bead c on its upper face.

Specification of Letters Patent.

Patented Dec. 31, T3912. Renewed September 25, 1912. Serial No. 722,369.

Upon the upper face of the base A intermediate the cup B and the bead ais fixed an annular layer or pad, D, preferably of cork, upon which thelower edges of the rings 0 rest when the telescoping member B iscollapsed.

A housing or cover F is provided, comprising a preferably concavo convexbody, f, and a side f provided near its marginal edge with a resilientdownwardly and inwardly annular internal curved flange f which forms aseat for the bead, a, of the base, as shown in Fig. 3.

In order to remove the base from its seat a releasing wedge is providedcomprising a plate G loose in an opening g, in margin of the side f ofthe housing slightly above the plane of the flange F. This plate extendsexterior of the housing wall f and is pro vided upon its inner edge witha bevel 9 adapted to contact with the curved under surface of the bead aand expel the base A from its seat when the plate is inwardly pressed.Integral with and soldered to the bottom of the plate G is a springplate H provided at its opposite end with a bent end portion k solderedto the inner face of the housing body f. The spring arm H whose act-ionend is pressed against the wall f normally presses the plate Goutwardly.

It will be observed that substantially all of the operative parts of thedescribed fastening devices are concealed; that it is possible topreserve a substantially unbroken sym-' metrical exterior contour in theentire structure.

The inner face of the body f of the housing F has resting thereagainstor affixed. thereto by any convenient means a sheet or pad J of cork orother non-metallic material adapted, to receive any impact from the bead0 when the parts are jarred. It will be observed that the members D andJ combine to deaden or prevent any rattle or sound from the housed partswhen the structure is moved or is carried in the pocket.

An examination of Fig. 7 will indicate that when desired the base A ofthe cup may be reversed from its position shown in Fig. 3 in which casethe housing F serves as a standard or supplemental base for the cupmember. The base proper, A, is now held in its seat as before by thecatch.

The completed structure is compact, and the exclusion of dust rendersthe same sanitary.

What I claim is,

A drinking cup embodying a base plate with a marginal bead, acollapsible cup on said base plate, a housing member inclosing the cupand comprising a body portion with a side provided near its marginaledge with a resilient internal curved flange forming a seat for saidbeach and means for releasing said bead from its seat comprising aspring 10 plate having a portion secured to the inner face of said bodyand a releasing wedge movable with said spring plate and having aportion projecting through the side wall of the housing.

In testimony whereof I have aflixed my signature in presence of twowitnesses.
